ROTARY PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 776,263, dated November 29, 1904.

Application iiled May 18, 1904.

T0 all whom, it 111,614/ concer/z:

Be it known that I, ALBERT SAUVE, civil engineer, a citizen of the Republic of France, residing at Union Works, 60 Park street, Southwark, in the county of Surrey, England, have invented new and useful Improvements in Rotary Printing-Machines, of which the following is a specification.

rIhe present invention relates to the combination of what is known as a nfixed-sized rotary printingmachine with an all-sized machine with the object of enabling the same set of printing-cylinders to be utilized for both machines and a diverting arrangement for directing the printed sheets to one delivery in the case of fixed-sized printing` and to another delivery in the case of all-sized printing, the speed production of the delivery apparatus of the two machines being of course adjusted to suit the respective sorts of printmg.

By the term fixed-sized, herein applied to printing-machines, I mean those in which only one uniform size of sheet is printed, in which case the continuous paper web is completely printed before being severed into separate sheets. In what are known as all-sized machines printed sheets of varying sizes are turned out, in which case the sheets are severed from the web before printing, the separated sheets being transferred from one cylinder toanother by the usual auxiliary means. By my improvement one machine is adapted to turn out either style of work by combining therewith separate delivery apparatus suitable for each kind-of work, either of which can be brought into use as occasion requires.

A suitable manner of carrying my invention into effect is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation showing diagrammatically the machine with a set of cylinders to be used for printing either fixedsized orall-sized papers and the delivery apparatus for the latter, and Fig. 2 is an end view of the delivery apparatus for the fixed-sized Fig. 3 shows diagrammatically a slight modification of the ar- Serial No. 208,572. (No model.)

rangement of cutting and folding cylinders employed in connection with the delivery apparatus for the fixed-sized sheets. Fig. 4 is a transverse section of one of the blanket or impression cylinders as arranged when using the machine for fixed-sized publications, and Fig. 5 is a longitudinal section thereof. Fig. 6 is a transverse section of such blanket or impression cylinder as arranged Vfor all-sized publications. Fig. 7 is a side elevation showing a suitable arrangement of tapes for conveying the sheets severed from the web before printing from the cutting-cylinders to the first printing-cylinder. Fig. 8 is a side elevation showing a suitable arrangement of tapes for conveying the sheets severed from the web before printing from the last foldingeylind er to the delivery-table after such sheets have been printed and folded.

Referring to Figs. 1 and 2, 1 is the reel of paper from which the web 2 is led over the tension and feed rollers 3, 4, 5, 6, and 7 botween the cutting-cylinders 8 and 9 and thence to the printing-cylinders 10, 11, 12, and 13, of which cylinder l() is the plate-cylinder for one side of the sheet and 13 the plate-cylinder for the other side of the sheet, (such cylinders being fitted with the usual ink-distributing system 14 and 15, respectively,) while cylinders 11 and 12 are the impression-cyl-` inders. In the case of fixed-sized publications the cutting-cylinders 8 and 9 remain inoperative and the web of paperQ proceeds in a continuous length through the set of printing-cylinders 10, 11, 12, and 13 and is conducted from cylinder 12 over suitable rollers 16, 17, and 18 to the delivery apparatus to be hereinafter described. Vhen cylinders 8 and 9 are not in use, they are rendered inoperative by simply moving them apart in the manner well known to the art, so that they do not come' in contact with thev web of pa`- per, and consequently do not divide it. In the case, however, of allsized sheets the cutting-cylinders 8 and 9 are actuated so as to divide the web into sheets of the required size., which are conveyed between tapes in the well-known manner to printing-cylinders lO 11 12 13. The cutting-cylinders 8 and 9 are constructed and operated so as to sever the particular length of paper from the web desired.

Fig. 7 shows a suitable arrangement of tapes 47 48 49 for conveying the sheets severed from the web 2 from the cutters 8 9 to the cylinder 11, said tapes each passing respectively over a set of rollers 47 X, 48X, and

49X, actuated in any convenient manner. When the machine is required to print a continuous web, the tapes 47 48 are movedout of Contact, so as to permit said web to pass freely between them.

In the drawings the tailed arrows a represent the path of travel of thecontinuous web of paper through the machine for fixed-sized publications, and the tailless arrows that of the sheets of paper for all-sized publications.

In the case of all-sized publications the lsheets of paper after being printed on the two sides by passing between the cylinders 10, 11, 12, and 13 are seized by the grippers of cylinder 19 and transferred in succession to the folding-cylinders 2O 21 22, from the latter of which they are conveyed by tapes passing over suitable cylinders 23 24, as shown at 2*, to the delivery-table 25, where they are deposited by the flier 26.

A suitable arrangement of tapes for conveying the sheets from the cylinder 22 to the delivery-table 25 is shown in Fig. 8 and consists in a set of tapes 50, passing around cylinder 22 and roller 51, a second set of tapes 52 also passing around roller 51 and rollers 53, 54, 55, 56, and 57, and a third set of tapes 58 also passing around rollers 57 and 56, above referred to, and then around rollers 59 and 6() and cylinder 22. The sheets will pass from cylinder 22 between tapes 50 and 58, and thence between tapes 52 and 58, which convey them to the delivery-table 25, and when they come opposite said table they are deposited thereon by the flier 26.

In the case of the fixed-sized publication the continuous web of paper, as above stated, is conveyed over the rollers 16 17 18, the latter of which may serve as slitters to divide such continuous web longitudinally in the direction of its length, after which, as shown in Fig. 2, the different sections are caused to pass over turning-bars 27 28 29 30 31, constructed and operated in the well-known manner, and the whole of same being superposed or collected and caused to pass through the cutting and folding cylinders 32 3'3 34, from the latter of which they are delivered' to the reception-table 35 by means of the revolving delivery apparatus 36.

In the arrangement shown in Fig. 2 the continuous web of paper 2 is supposed to be split or cut into four longitudinal sections, and these are superposed or collected together with a fifth section 2, supplied from a supplementary reel and which is incorporated with the other four sections and is severed and folded with them, so as to constitute the cover of the finished publication. It will thus be seen that in Fig. 2 the four superposed sections of the continuous web 2, together with the supplementary section 2, will be severed between cylinders 32 and 33 and receive a fold between cylinders 33 and 34 and are then delivered to the delivery-table 35 by the revolving apparatus 36. These four superposed sections of web 2 and supplementary web 2L can, according to the size of publication required, either be cut twice during each revolution of cylinder 32, in which case such cylinder will be provided with two cutters or saws 37 -38, acting in conjunction with corresponding counterparts 39 40, carried by cylinder 33, or such superposed sections may receive a single cut only per revolution of cylinder 32, in which latter case such cylinder 32, as shown in Fig. 3, will be provided with one cutter 37 only, the cutter 38 being replaced by an engaging blade 41, while the counterpart 40 with which cylinder 33 was provided in the preceding arrangement will be replaced by a seizing-blade 42.

Referring to the detail views, Figs. 4, 5, and 6 of the impression or blanket cylinders 11 and 12, it will be understood that in the case of an all-sized sheet a gap or opening must, as shown in Fig. 6, be left in the periphery of each cylinder for the play of the seizing-blades 43 for gripping the forward edge of each sheet, while the .presence of such gap in the case of Xed -sized sheets is objectionable and must, as shown in Figs. 4 and 5, be filled in, for which purpose a filling-in piece 44 is inserted in such gap or opening and secured in position by end cheeks 45 and bolts 46.

It will be fully understood that in the case IOO of a Xed or full sized paper the machine will operate in the ordinary manner, the whole of the circumference of the printing-cylinders 10 and 13 being utilized, while in the case of it being desired to vary the size only the requisite portion of the circumference of these same printing-cylinders will be operative or doing effective work and, further, that in the rst case the sheets will be delivered at the point 35, appointed for the full-sized sheets, and in the latter at the point 25, appointed for the smaller or all-sized sheets.

It will be readily understood that when the one delivery apparatus is in operation the other is disconnected or thrown out of gear.

What I claim as my invention, and desire to secure by Letters Patent, is-
